<p>You can specify a range of consecutive values in a single <code class="code">case</code> label,
like this:
</p>
<div class="example smallexample">
<pre class="example-preformatted">case <var class="var">low</var> ... <var class="var">high</var>:
</pre></div>

<p>This has the same effect as the proper number of individual <code class="code">case</code>
labels, one for each integer value from <var class="var">low</var> to <var class="var">high</var>, inclusive.
</p>
<p>This feature is especially useful for ranges of ASCII character codes:
</p>
<div class="example smallexample">
<pre class="example-preformatted">case 'A' ... 'Z':
</pre></div>

<p><strong class="strong">Be careful:</strong> Write spaces around the <code class="code">...</code>, for otherwise
it may be parsed wrong when you use it with integer values.  For example,
write this:
</p>
<div class="example smallexample">
<pre class="example-preformatted">case 1 ... 5:
</pre></div>

<p>rather than this:
</p>
<div class="example smallexample">
<pre class="example-preformatted">case 1...5:
</pre></div>

</div>
